Is it safe to use 150 hp shot ??

[HADI-ZR1]

is it safe to spray 150 hp nitrous in stock Lt-5??:icon_scra
who try it?

[jonszr1]

hadi, from what corey has told me you can get away with a 50 shot but after that the tune gets dicey.

[Kevin]

nos made a kit in conjunction with GM that was a 125 shot

[jonszr1]

was there a new prom that came with it? if not i would not personally want to use that much nitros without backing some timing out of the car and cking the fuel curve. better to be cautous than to have parts scattered all over the place. JMHO:mrgreen:

[HADI-ZR1]

:rolleyes:
but i used 100 shot more than 20 times without any problem on motor!:D

i have DRM chip on my car.
retarding timeing curve will kill the power jmho :icon_scra

[jonszr1]

hadi you might get away with 100 shot but the ? was 150 and to that from those who i asked you better watch out . things get melted if you dont ck the tune. in the end others can do what ever they want . i dont like nitros. hp in a bottle if the bottle is empty then you loose all that hp . i prefer to have what ever hp there all the time without haveing to fill a bottle . to me its engine killer . i would prefer a supercharger or a turbo as a power adder. it just my thoughts no offence intended:mrgreen:

Hadi.... whassup, bro??! I noticed your post, and it got me thinking
instead of using a 150 shot of this.... http://i76.photobucket.com/albums/j9/kmoudy/cartoons/nos.gif

what?:mrgreen:

[GrayZ]

Haid, i'll trade you a turbonator for a windshield

[jonszr1]

Hadi ,now thats a deal?????????????????????????????????????????????? ????????:mrgreen:

[HADI-ZR1]

Haid, i'll trade you a turbonator for a windshield
:mrgreen: no thanx.

see i also bought new winshield just in case, cuz you know those winshield hard to find!! :icon_scra .

[HADI-ZR1]

Hadi ,now thats a deal?????????????????????????????????????????????? ????????:mrgreen:
:-D

today i changed the alterantor with light wieght uderdrive pulley and new belt,just after 2 days from my arrive to czech Rep. after 5 days going to change Water P. pulley too.
today i smoke my wheels in every road ,7000 rpm shifting is true life!!:mrgreen:
:cry: after 3 weeks i am gona miss my zr again....

Hadi:
glad to hear you are getting some seat time in your
beloved ZR1, of course, you know i was yanking your chain. But, if it's power you are looking for, you might
consider the raptor TT system, once they start marketing
it, I know the owner's are stand up, honest people.
It will do what they claim, once it has been tested.
Enjoy you're car :thumbsup:

Hello Bro.
well, i still perfer C/S :mrgreen: , i am supercharger guy!
easy to change pulley and play with bost.
it is nice setup Rear TT , but man, did you hear how noizy is that car?? :p
and ppl said that Turbo will reduce sound , COME ON!!! :mrgreen:
just fix mufller and go ....:hello:

[djpatrick35]

Would a 50/75 shot be OK for occasional use? And if so, what is the difficulty level of installing a NOS system in the ZR-1?

[RHanselman]

Corey had Curtis Ward's car setup for lots of NOS. I believe he was in the 250 shot arena??

Curtis's car was a stock block 91 with porting, headers, and a tune. Not sure what else but I know the bottom end was stock.

BTW - the stock pistons have a 250 thousands think top which is great for NOS, it's just the head gasket sealing that's worrysome...

Hadi,

The rear TT car is actually music to the ears and not real loud at all. It's kind of like a B&B without headers on the outside and a Corsa in the cockpit i.e. no resonance. You can drive long distance with the windows up and only hear the turbos sing when you accelerate. To hear the rest of the symphony you have to roll down the windows.

BTW - I just drove it yesterday, it makes you smile from ear to ear...

now taken this post in thread from CF ! :icon_scra
The STS kits look like a good deal, here is a list of my opinion of them, and why I don't sell them anymore:

1. STS claims that heat is not required to help spool the turbo, that exhaust velocity does the job.
Major retailers of the STS kits sell the kits with exhaust wrap, to help spool the turbo. We have done this at our shop, and it helps quite a bit. It is obvious that the closer to the engine the turbo is mounted, the more efficient it is going to be.

I copied this from the STS website.

"Doesn't heat create the velocity in the exhaust gasses to spool the turbo?
No, heat doesn't create velocity. Heat creates volume. If you look at any of the physics laws for gasses, you will find that pressure and volume and heat are related. PV=NRT is a popular one, The V isn't for velocity, it is for Volume.

The turbine housing is what creates the velocity. The scrolling design that reduces the volume of the exhaust chamber as it scrolls around causes the gasses to have to increase in velocity and pressure to maintain the same flow rate.

Hotter gasses have more volume, thus requiring a higher A/R which in effect means that it starts at say 3" and scrolls down to approximately 1". Lower temperature gasses are denser and have less volume, so they require a lower A/R housing which would start at the same 3" volume, as the turbine housings use standard flanges, and scroll down to say 3/4".

Now if you were to reverse the housings in application, the conventional turbo would spool up extremely quick, at say around 1500 rpm but would cause too much backpressure at higher rpms because the higher volume of gas couldn't squeeze through the 3/4" hole without requiring a lot of pressure to force it through. On the reverse side, the remote mounted turbo with its cooler denser gasses, wouldn't spool up till say around 4000 rpms but once spooled up would make efficient power because it doesn't require hardly any backpressure to push the lower volume of gas through the larger 1" hole."

So I take it the exhaust wrap should not make a difference?

2. You don't want to run catalytic converters with a rear mount turbo. Years ago a guy brought in a Ferrari to us that had a rear mount turbo. One of the catalytic converters internals came apart, as they sometimes do, and parts of it lodged into the turbo, ruining it. I predict that this will be happening to the STS turbo customers.

3. The oil return line is routed into the passenger side oil cap on the STS kits. This line has a habit of coming loose, and spraying oil into the engine compartment. It happened to us, and I have read where it has happened to other people.
These engines already have enough oil returning down through the heads, they don't need more! This is a bad design, and many people are rerouting the oil return line to the oil pan, where it should be in the first place. The problem with running the line to the pan is now you have to drill or punch a hole into the oil pan to run the oil line, unless you remove the oil pan. We recently removed the oil pan on a customer's car, and welded a bung into the pan for the oil return line.

4. The turbo hangs without brackets supporting it, and will sag over time. We add a bracket when we install these kits, I don't link seeing the turbo dangling there.

5. The air filter is in a bad location, as is susceptible to dust, water, dirt, etc. STS offers a cover that goes over the filter, but we found the cover seriously hinders performance. We proved that on our chassis dyno.

6. On the F Body STS kit, a driver side subframe connector cannot be used. STS claims their plumbing that is routed down the driver side does the job of a subframe connector. We find that humorous, at best!

7. The plumbing underneath the car hangs too low in my opinion, and you don't want a lowered car with an STS kit on it.

8. The silicone couplers that are provided with an STS front mount intercooler are thin, and we had two of them blow apart. The intercooler plumbing that was provided with the front mount intercooler option that we ordered for a customer's car was poorly routed, we ended up using our tubing from our front mount kits that we sell.

9. The oil lines sure have a long way to run, from the front to the rear, and back up front. If a leak developed, it could be a quick way to ruin an engine.

10. It would be relatively easy for someone to slide underneath the rear of an STS equipped car, and steal someones turbo.

11. The boost line running back up to the engine from the turbo has silicone couplers at various points along the way, and can blow apart.

12. Any exhaust leaks will diminish the efficiency of a rear mount turbo.

hadi , i believe ron has just used the base kit as a guide line . i believe they took alot of time to make their zr1 kit a good one with good parts and routing . they spent alot of time really thinking this thing out . when they come out with a kit i think i just might get one . hope this helps

[rogerzr1]

Brad, any idea what the price range will be?

[bradslt5]

roger, no i dont you would have to ask ron . i just know he is a class act and took alot of time to do the project right. they will also not offer anything till they are totally happy with it .

[HADI-ZR1]

So thats why the Vendor EPP in CF stop selling them ! :rolleyes:

[bradslt5]

hadi , who is epp? ron has not offered his kit for sale yet to my knowledge

[HADI-ZR1]

EPP is a vedndor in CF ! here his web:

I'm assumming you're talking about a wet kit and not a old school dry kit?

Call n/x and order a GM efi kit with heater and you'll be just fine! The old dry kits rely on the fuel pressure regulator to bump the injector cycle up wich as you know can be an issue with lt5 injection.......where as a wet kit has its own fuel supply from the fuel rail!

As long as you keep it at 100-150hp max you'll be just fine if you don't get greedy.:mrgreen:

Speaking from experience the 100hp n/x wet kit hits twice as hard as the old 100hp dry 1980's technology nos kit!!!

[HADI-ZR1]

Destroyer , for 2 years i have NX kit on my Z :p

but still i didnt use 150 Hp ,sometimes i used 100hp maybe 10 shots during 2 years,
and i wished that someday i see 06Z06 by my side to show him the race!:mrgreen:
MAN the Zr1 with 100 shot is Scary run !!

[bradslt5]

Hadi, i have never used nitros , what it like when you hit the button , its it an all of a sudden wosh or what ?

[Polo-1]

It's on.....It's off.. just like a light switch. you can play with the throttle (on- off) or the arm switch. either way, jucie is on or off.

[HADI-ZR1]

guys, the fakt is that refilling Nitrous cost me $120 in Czech Rep. ! wtf!!

in kuwait we refill it for less than $25 !! :mrgreen:

so how much will be in USA ? hmm.

[HADI-ZR1]

Hadi, i have never used nitros , what it like when you hit the button , its it an all of a sudden wosh or what ?

brad, in first you will see losing traction..., when the rear tires hook on the road at 2 shift and 3rd you will feel the engine wana split from the chassi...

during shifting 1-2 ,you could lose control. driver must be very careful in this moment.:thumbsup:

tell you what, when you accelerate from standing stop, how much time in seconds to reach 7000 in first
shift ?? so imagine now with nitrous ,the time cut in half...very very fast with 32valvz! :-))
i have Progressive Nitrous Controller from NOS, new never been used. i think i going to sell it, i havent time to fix it !

[Polo-1]

so how much will be in USA ? hmm.


$4.50 a lb retail 15lb bottle $67.50
$2.15 a lb good guy price $32.25

I sprayed 225 so I could beat Bob Hall. Properly set up with a window switch, it seemed to work just fine for me. I very seldom used it on the street just at the strip so it was in a controlled environment. And I was using slicks to get it going. It ran a best of 11.08 @ 129 with a 1.59 60' time when it was not running too great. Later, when Corey got #364 all running right, I feel sure it would have been in the 10's. But that never got to happen. Window switch is very important in my opinion.
